What is a Shunt Resistor?

Shunt resistance definition

A shunt resistor is a high-precision resistor that uses a very low ammeter resistance to measure the flow of current through a circuit. It is the resistance of a conductor in parallel with a circuit. Because of its particularity, it is generally used in precision electronic products. The smaller the resistance value of the shunt resistance, the more obvious the shunt effect.

What is an Inductive Ballast?Inductive Ballast definitionInductive Ballast is an iron core inductance coil, the nature of inductance is that when the current in the coil changes, it will cause a change in magnetic flux in the coil, resulting in induced electromotive force, and its direction is opposite to the direction of the current change, thus hindering the current change.Working principle of Inductive BallastWhen the 220V 50Hz AC power supply is applied in the switch closing circuit, the cur

What is Inductance?

What is Inductance?

What is Inductance?Inductance definitionA property of a conductor measured by the ratio of the induced electromotive force or voltage in the conductor to the rate of change of the current that produces it. A constant current produces a stable magnetic field, a changing current (AC) or a fluctuating DC produces a changing magnetic field, which in turn induces electromotive force on a conductor in this magnetic field. The magnitude of the induced electromotive force is proportional to the rate of

Shunt Resistor: What is it And How Does it Work?

Shunt Resistor: What is it And How Does it Work?

What is a Shunt Resistor?A shunt resistor (or shunt) is defined as a device that creates a low resistance path to force most of the electric current through the circuit to flow through this path. In most cases, a shunt resistor is made up of a material having a low-temperature coefficient of resistance, giving it a very low resistance over a wide temperature range.Shunt resistors are commonly used in current measuring devices called “ammeters”. In an ammeter, the shunt resistance is connected in
